IMPROVEMENT IN SHOT-CARTRIDGES.

Y Specication forming part of Letters Patent No. 157,793, dated December 15, 1874 applicationllil'ed.

November 7, 1874.

To all 'whom it may Be it known that I, JOHN W. COCHRAN, of

the City, county, and State of NewifXork, have invented Improvements inl Shot-Cartridges, of

which the following is a specification.;

The object of this invention is to prevent the scattering of the shot, and the leading of the bore of the gun, and also to facilitate the` reloading of the cartridge-case when it is desired to use it over again; and to this end`it consists inthe combination, with a double expanding wad introduced between the powder and shot, of au attached tube or case, which .is independent of the outer case or case proper, for the charge of shot.

Figure 1, in the accompanying drawing, is a longitudinal View, partlyA in section, of a complete cartridge illustrating both features Of this invention. Fig. 2 is a central longitudinal section Of the combined double expanding wad and shot-case. Fig. 3 is a eent-ral section of the expanding wad without an attached shot-case.

Similar letters of reference indicate corresponding parts in the several figures.

A is the case of the cartridge, which may be made wholly of metal, Or with a'luetallie head and a tube of paper Or other material, and may be primed in any suitable manner. B is the double expanding wad, which is placed between the powder, a, and shot, b. This wad has its front and rear both concave or cup-shaped. Its external circumference is such that it may, in its normal condition, lit snugly into the interior ofthe tube -of the case A. This wad may be made of paper, by first cutting a long and slightly-taper strip of paper, and rolling up the said strip tightly, commencing at its narrower end, and afterward placing the roll into a die of suitable form', and subjecting it to pressure in an axial direction, whereby the several layers are slnrred into each other, and so made to bind thempurpose of containing'I the selves together, and the` whole roll is compaeted into a hard andsolidmass resembling papier-mache.

When the said wad is made with an attached n shot-ease, c, as shown in Figs. 4l and 2, it mayV be made of a strip in the same manner, apor`` tion of the strip atthe wider end being made parallel, or with one edge parallel, with the center of the strip, the said wider portion, on being rolled up, forming the ease c. The eas# c may, however, be made of paper or othe material, and attached to the wad by adhesive material Or Otherwise.

When the shot-ease and double expanding wad are thus constructed Or Combined, a nnlnf ber Of such casesl with' attached wads may be kept On hand loaded withshot, which may be -confined therein by a separate wad,'d, inserted into the mouth of the case, asshown iu Fig. 2. AWhen the cartridge-case A isV loaded or reloaded, Oue Of the loaded cases e, with its attached wad, may be inserted on the top or in front Of the charge of powder, and conlined by an additional wad, e, inserted into the month of the case A, as'shown in Fig. 1.

When the double expanding wad is made without an, attached shotrcase, as Shown in Fig. 3, the said wad isA inserted into the eartridge-'ca-se A after the charge of powder, and the shot are there inserted On the top or in front Of the said wad directly into the ease A, and confined by a wad inserted into the front of the case.

What I claim as my invention, and desire to secure by' Letters Patent, is-

The combination of the double expanding wad with an attached shot-case, substantially as and for the purpose herein specilied.A
